riscv: un-cache the `avl` and `vtype` when returning from a function call
the csrs `avl` and `vtype` are considered caller-saved so it could have changed while inside of the function. the easiest way to handle this is to just set the cached `vtype` and `avl` to null, so that the next time something needs to set it, it'll emit an instruction instead of relying on a potentially invalid setting.
